Patent CA-2233455-A1 (CA)
Inventor: BEARDWOOD EDWARD S
IPC: G01N17/02
Filed: 1996-09-27
Abstract: La présente invetion concerne un procédé de détection d'encrassement microbiologique dans un système aqueux, lequel procédé consiste à déterminer un taux de corrosion de référence, le taux de corrosion étant contrôlé de manière continue. On mesure tout changement du taux de corrosion ainsi que le taux de corrosion maximal, ceci avant de déterminer un facteur d'encrassement de référence en mesurant et en contrôlant les paramètres d'un fluide dans le système aqueux. Toute élévation du facteur de corrosion au-dessus de la référence est ensuite détectée. Tout changement dans le taux de corrosion est intégré, dans le temps, à un intervalle allant du moment où le taux de corrosion de référence est déterminé au moment où le taux de corrosion maximal est atteint. Tout changement dans le facteur d'encrassement est intégré, dans le temps, à un intervalle allant du moment où le facteur d'encrassement de référence est déterminé au moment où une élévation du facteur d'encrassement est détectée. Le facteur d'encrassement et le taux de corrosion sont enfin comparés afin de déterminer si l'encrassement est de type microbiologique.

Abstract: The air brake assembly on commercial vehicles presently require the truck driver to determine, manually, whether the slack adjusters are out-of-adjustment regardless of whether there is a manual or automatic slack adjuster system in place. There is no cab display that alerts drivers of air braked commercial vehicles when maintenance related brake problems have reduced the retarding capacity of the brake system of the commercial vehicle. The "Brake Alert" with reduce the subjective nature of the detection system for non-fuctioning air brake assemblies and will provide an early warning system to notify drivers of commercial vehicles that the air brake assemblies of the commercial vehicle may not be functioning within normal limits. In this invention, a series of or one gauging system will be attached to the pushrod, s-cam shaft, brake lining and/or brake chamber of each air brake assembly on a commercial vehicle. If the push rod extends beyond the maximum allowed distance on application of the service (foundation) brakes then a switch will activate a warning light in the cab of the commercial vehicle. Equally, if the s-cam shaft does not rotate within normal limits when the service (foundation) brake is applied then a switch will activate a warning light in the cab of the commercial vehicle.  Still yet, if the brake application does not generate a minimum temperature rise gradient upon application of the service (foundation) brake then a switch will activate a warning light in the cab of the commercial vehicle. The driver, will, in turn, be notified that a particular brake assembly is not functioning within normal limits and a manual check and/or adjustment is needed immediately. In higher end models, a monitoring system will be attached to the gauging system(s) to record a history of the brake assembly malfunctions, which monitoring system can be accessed by a motor vehicle inspector, the owner of the commercial vehicle and/or the operator of the commercial vehicle.

Title: Inhalator designed to provide multiple doses of a dry pharmacological powder
Inventor: EGGIMANN THOMAS
IPC: A61M15/06
Filed: 1996-12-05
Abstract: The inhalator proposed has a casing (100, 150) to which is fitted a special mouthpiece (900) covered by a removable protective cap (950). Disposed inside the casing are a slide valve guide rail (200), a metering slide valve (300), a closure (400), a slide (500), a funnel (600), a counter (700), a valve cover (800) and a valve guide (850).

IPC: G06Q20/00
Filed: 1997-12-12
Abstract: The present invention relates to electronic monetary systems in general, and in particular to measures for making their use easier for an average user. The present invention is based on the idea that the use of electronic money is greatly simplified for a non-expert user, if the Internet Service Provider of the user takes care of the payments, and adds corresponding charges on the user's telephone bill. Such functionality inquires the intervention of the ISP in the transmissions between a user and a third party, i.e. intercepting the electronic payment requests sent by a merchant. According to the present invention, the ISP uses electronic money on behalf of the user, and charges the payments on the user's telephone bill. The ISP can take care of all technical details necessary for obtaining different forms of electronic money in a centralized manner, and all users of the ISP can use the electronic money obtained by the ISP simply by allowing the ISP to add corresponding charges to their telephone bills. Further, the ISP can obtain all major forms of electronic money, whereafter a user can choose the most economical way of payment, if a merchant accepts payments in more than one form of electronic money.
